I guess those early morning flights from "east" U.S/Canada to Europe are only heading LHR by now ...

After Concorde flights stopped in 2003, Air France tried to relaunch a daylight flight to CDG during the 2007 summer season : AF005 JFK. 07:05AM ---> CDG. 09:00PM (Daily A330-200).
The results were not the one expected and this experience was stopped at the end of the season.
